Example 1: When ordering a product with model name: 2725T, frequency: 125 MHz,
frequency stability: ±100 x 10
–6
, and power supply voltage: 3.3 V
When ordering our products, specify them with an “Ordering Code” that consists of the following:
Ordering Code: 2725T – 125.000000M – NSA6293A
Model name – Frequency (up to 9 digits) M – Number for specifying an order
If you have any queries concerning our standard frequencies and numbers for specifying orders, please contact our sales representatives or visit our homepage (http://www.ndk.com/).
